scanning watermarks
hello all,
I'm trying to get a decent digital image of a watermark with my scanner. My method is still not perfect although I manage to see the watermark but not very clear. I'd appreciate very much if anyone could help me or provide directions in achieving this goal in a better way. Thanks, pedro |

Thanks, pedro Found in the RCSD archive but Pedro won't be able to read this answer due to his killing instincts: -------------------- Hi, After a little trial and error I've found a way to get nice JPG's of watermarks. 1) Place the stamp face down on the bottom of a watermark tray (the smooth side) and saturate with fluid. 2) Place the tray face up on the scanner. 3) Set the scan margins a little bit inside the borders of the stamp, so none of the tray shows. 4) Scan at hi-res and manipulate the image as desired. The images are very clear, although not as clear as in Scott, makes me wonder if the wmk images they use are hand drawn or cleaned up somehow. Anyone else do this? --Bob Russell ------------------------------ -- Victor Manta, PWO, AIJP ---------------------------------------------------------------------------- Philatelic Webmasters Organization: http://pwmo.org/ Art on Stamps: http://artonstamps.org/ Romania by Stamps: http://marci-postale.com/ Communism on Stamps: http://reds-on.postalstamps.biz/ Spanish North Africa: http://www.sna-on.postalstamps.biz/ ---------------------------------------------------------------------------- |

Bill Bob's posting is, if I remember well, from 1998. Maybe then the trays were transparent. -- Victor Manta, PWO, AIJP ---------------------------------------------------------------------------- Philatelic Webmasters Organization: http://pwmo.org/ Art on Stamps: http://artonstamps.org/ Romania by Stamps: http://marci-postale.com/ Communism on Stamps: http://reds-on.postalstamps.biz/ Spanish North Africa: http://www.sna-on.postalstamps.biz/ ---------------------------------------------------------------------------- |

Thanks, pedro IF your scanner will scan photographic negatives, place the stamp face UP and make the scan. You'll have to severely manipulate the contrast and black/white capture points while scanning, but for many watermarks this will work. Note, it will be 'reversed' so additional work in your graphics editor will be needed. Thanks for your answer, I'll give it a try regards, Pedro |

Bill Hello, Sit F. was probably talking about a transparent tray, like a petri dish, for instance. The problem here is how to obtain good quality images of the watermark using a scanner. That will allow me to send the result via email, for example to discuss with other stamp collector fellows about which watermark in the catalog corresponds to my stamp's. Many times watermarks are not clearly visible, and identification could be very hard, but with the opinion of others perhaps one can have a better idea about which is it. best regards, Pedro |

His proposal is relevant for the discussed topic. The advantage of using computer readable images of stamps, watermarks, perforations, etc. is obvious. Just to notice that from the points 1) and 2) of Bob's posting I infer that finally the back of the stamp should face, through the transparent tray, the scanner's plate. Here is another relevant posting from the archive, posted in 2006 by Jay Carrigan: "My technique is to dip the stamp in watermark fluid, slip in into an oversized black mount and quickly scan it before it dries. No further manipulation required. Here's a scan of a Germany stamp with a reversed watermark variety: http://www.jaypex.com/Germany/587Y.jpg. " The link still works! If a good soul comments on my posting then Pedro will be able to read it and maybe think twice as well about his understanding of some things written here as about who is losing what by "killing" participants. -- Victor Manta, PWO, AIJP ---------------------------------------------------------------------------- Philatelic Webmasters Organization: http://pwmo.org/ Art on Stamps: http://artonstamps.org/ Romania by Stamps: http://marci-postale.com/ Communism on Stamps: http://reds-on.postalstamps.biz/ Spanish North Africa: http://www.sna-on.postalstamps.biz/ ---------------------------------------------------------------------------- |

Yep but with macro lens and lighting accessories and something that holds the whole equipment. Plus probably the stamp saturated in watermark fluid. Victor Manta |

Not the same definition as a scanner. A scanner can provide much better quality and more detailed images when scanning at a high resolution. Sometimes a simple eye inspection cannot identify clearly the watermarks A scanner can be used as a microscope with my higher resolution than a digital camera or a samrt phone. Digital cameras/ smartphones are like more sophisticated replacement of human eye but not so perfect as a scanner. regards, Pedro regards, Pedro |

You may need a stand for the camera and some supplementary lighting to get the best possible picture. You can zoom a digital photo as well as a stamp image. Bill |
